i don’t even really tow much. Just have a heavy rig I guess. I only exceed 200 on long. slow, steep hills when it’s over 90 degrees, yet even with a heat generating 7.3, I rarely reach temps that concern with coolant or oil. Which is weird to me, but I’ll take it, lol. I choose the cooler over the pan on recommendations and results that others claimed with pans vs coolers. I’m sure it varies greatly though.
Either way totally agree on dropping the pan if for no other reason then replacing the filter. Especially if you don’t know the last time it was done.
